[Method] Taking sugarcane variety ROC22 as tested material,coupling effects of different levels of water supply quantity and different levels of phosphorus fertilizer on the yield and quality of sugarcane were studied. Among them,water supply quantity had 3 levels,that was,the water supply quantity per 10 days from the early tillering stage of sugarcane to the end of elongation was 199.5 m3/hm2 (A1),400.5 m3/hm2 (A2) and 600.0 m3/hm2 (A3),respectively; Phosphorus fertilizer as basic fertilizer had 4 levels:P2O5 0 kg/hm2 (B1),120 kg/hm2 (B2),240 kg/hm2 (B3) and 360 kg/hm2 (B4). [Result] Treatment A3B2 in water-fertilizer coupling was more suitable to improve economic traits of sugarcane. [Conclusion] The research results provide theoretical basis for the efficient utilization of water and phosphorus fertilizer in production of Guangxi sugarcane and the cultivation of high-yield and high-glucose sugarcane.展开更多

Different stages of the induced spontaneous combustion process were studied by integrating wavelet technology and nonlinear dynamics theory. The results show that ignition points of all the ore samples are above 330 ℃, indicating that sulfide ores of the pyrite mine are difficult to combust spontaneously under normal mining conditions. Spontaneous combustion process includes three stages: incubation stage, development stage and approaching stage. The average temperature rising rate of the three stages are 1.0 ~C/min, 2.0 ~C/min and 4.2 ~C/min, respectively. During the spontaneous combustion process, mean values of approximate entropy and correlation dimension increase at first, and then decrease in the following stage. The mean value of the maximum Lyapunov exponent increases with the passage of reaction time. In a whole, correlation among the three nonlinear parameters firstly weakens, then enhances, and the best correlation period is at approaching stage. As ignition point increases, the maximum Lyapunov exponent of approaching stage decreases. Therefore, combustible tendency of sulfide ores could be qualitatively evaluated based on the maximum Lyapunov exponent of this stage.展开更多

Coleman contributed to this study largely, although Bourdieu introduced the concept of a theoretical understanding of capital varieties. He was interested in the convergence of social, cultural, and economic capital. The authors propose to focus on the cultural capital of both the qualitative characteristics of the state of society. The problem is that in the presence of cultural capital as a funded system of values in the form of works of art and science, society degrades morally. Any cultural capital based on traditional religious values. This does not mean the broadcasting of religious themes in works of art, although it excludes, but rather a philosophical position of artists and researchers, through which the public receives the interpretation of events, their assessment of a certain value-regulatory system of coordinates. This element is the spiritual capital of the company and is a fundamental element of cultural capital. Qualitative state of society, its morality depends on the amount of spiritual capital, which he occupies in the field of cultural capital. A striking example of how the degradation and spiritual revival of capital in society can serve as the processes that took place during the last century.展开更多

To accomplish this task effectively, we need to identify industries with potential comparative advantage. Using the latest data on international trade of products, this paper verifies the premise of heterogeneity of product space of the evolutionary theory of comparative advantage, and analyses the evolution of product space of China and most countries in the world. The paper makes predictions on China "s industries with potential comparative advantage in near terms using the product space theory, and carries out thorough discussion on the evolutionary track of industries under different proximity thresholds. The basic conclusion is that even as China's number of industries with comparative advantage is larger than the global average, its industrial upgrading capacity is limited, as it has fewer industries with potential comparative advantage and lower sustainability in the current sectors than the world average. China faces a dilemma in the process of industrial upgrading, as a rapid upgrading would cause a shock to current economic growth, and a slow one would not maintain sustainable growth. With limited industrial upgrading capacity, the best structure adjustment and upgrading strategy is to give full play to the advantage of China's industrial diversification and combination to achieve an inclusive upgrading.展开更多

It realizes the sublation of theory and ideology by means of critical, explanatory and constructive logic, displaying a unique theoretical originality. Lenin's theory of imperialism offers a theoretical reflection on the development of capitalism and its historical trends; it is a practical response to the world structural contradictions arising from imperialism, an epochal reflection that vigorously explores and constructs the value claims of a new civilization and provides in-depth Marxist view of world history. The methodology and general principles of Lenin's study of imperialism are based on the materialist view of history. They are not out of date, nor are the propositions in his theory of imperialism, based as they are on research into monopoly. At the same time as it declared war on the values, systems and practices of the old world, Lenin's theory provided a completely new cognitive method, philosophical attitude and ideal values for the future society. This has become the precious wealth of mankind, wealth that transcends historical time and space.展开更多
